PROJECTS

Rockford - Fraser Range: Nickel-Copper, Gold

HIGHLIGHTS

Extensive ground EM programme completed over

six target areas at Rockford Project, Fraser Range

Five conductors identified at Area D, with three

conductors having very high conductivities of

9,000-17,000S associated with large relatively

shallow bedrock features

Two further conductors identified at Areas E & F

OVERVIEW

Following the settlement of the 70% purchase of the

Rockford Project tenements from the Creasy Group on 23

September 2015, Legend conducted the first full quarter of

exploration consisting of data interpretation and ground EM

surveying.

The ground EM programmes were rewarded with seven

conductors in three separate locations. Three of the

conductors have very high conductivities and are relatively

shallow. This will mean that the cost of RC drill testing

these features will be at the modest end of the cost scale.

The RC programme is a priority activity for the current

quarter and will be complimented by completing the ground

EM programmes (which were interrupted by the Christmas

break) and later regional aircore drilling of circa 10,000m.

Full details of the work completed are summarised in the

body of this report and once new RC and aircore

programmes are finalised details will be released to ASX.

1. ROCKFORD PROJECT – (Fraser Range District) Nickel-Copper, Gold

The Rockford Project covering 2,939km2 comprises eight contiguous granted exploration licences

located in the highly prospective Fraser Range district of Western Australia (Figure 1). A large

portion of the Project (2,530km2) is the subject of a joint venture between Legend (70%) and Creasy

Group (30%), with Legend operator and manager of the joint venture, (see LEG:ASX

announcement 2 July 2015).

The project covers a strike length of 100km over a regional gravity high “ridge” associated with

dense mafic/ultramafic intrusive rocks of the Fraser Zone, within the larger Albany-Fraser Orogen.

The Nova-Bollinger deposit, which lies within the Fraser Zone, is situated on a similar tenor gravity

ridge to that of the Rockford Project, see Figure 1.

During the quarter, Legend undertook extensive moving loop electromagnetic (“MLEM”) surveying

over six target areas (Areas A Central, B, C, D, E & F), comprising 82 traverses, 1,978 stations and

covering 189.9 line km, see Figure 1.

The results from the MLEM surveying are considered highly encouraging with the identification of

five conductors at Area D and single conductors at both Area E and Area F. Descriptions of the

conductors from these three areas are provided below.

Area D

Area D has a discrete 1.5km x 1km gravity high (4mgal) with an associated magnetic signature

suggestive of a structural fold closure or intrusive feature. A total of 11 high powered (~200amp)

MLEM lines spaced 150/300m apart were completed, identifying five highly to moderate conductive

bedrock conductors at relatively shallow depth. Figure 2 shows the location of the five conductors

with respect to the discrete gravity high, with a summary provided in Table 1 below.

Table 1: Area D Conductor Description

Conductor Conductance Dimensions Depth to Top Plate Orientation

1 ~11,000S 800m x 800m+ ~100m 80 deg. NW dip

2 ~17,000S 800m x 800m+ ~200m 75-80 deg. N dip

3 ~9,000S 800m x 800m+ ~100m 75-80 deg. NW dip

4 ~1,000S 300m x 200m ~100m 85 deg. NW dip

5 ~5,000S +1,000m x 1,000m ~250-300m 85 deg. NW dip

Conductors 1, 2 and 3 all had very high conductance levels which required infill lines utilising lower

base frequencies (originally 1 Hz down to 0.5Hz & 0.125Hz) to better define the conductors and allow

accurate modelling. These conductors represent highly conductive bedrock sources and are situated

on the SE margin of the gravity high and appear related to local aeromagnetic units.

Maxwell modelling has characterised these three conductors as being of large areal size/extent

(>800x800m), striking ENE-WSW, having steep N/NW dips (75-800) and an estimated depth to top

of source of 100-200m. Conductance levels are very high at ~9,000-17,000S and consistent with

the signature of a well-developed sulphidic/graphitic body.

Conductor 4 represents a moderate strength, localised (~300x200m) conductor located within the

central zone of the gravity high. Moderate conductance levels of ~1,000S were apparent from

modelling, with the associated source having an estimated depth to top of source of 100m, orientated

NE-SW and dipping steeply NW at ~850.

Conductor 5 is a strong and deeper level bedrock conductor defined along the western margin of the

gravity high. Further definition of this target is required, however the associated conductive source/s

are situated at >250m depth to top and do not demonstrate any clear correlation with the gravity and

aeromagnetic data.

The highly conductive character of Conductors 1-3 and the location of Conductor 4 with respect to

the gravity feature make these conductors compelling RC drill targets.

Area E

Area E has a discrete 1.5km x 1.3km residual gravity high with associated strong magnetic response

representing a complex fold closure, see Figure 3. A major NW trending cross structure is also

interpreted to bound the gravity feature to the northeast and north.

Modelling of the MLEM data identified a large >1,500m x 1,500m late channel bedrock conductor

with low conductance (~250-500S), an estimated depth to top of source of >600m and is near flat

lying (summarised in Table 2). This is a low priority feature, however further modelling is required to

better define its parameters and determine whether it warrants drill testing.

Area F

Area F has an elongate ENE trending residual gravity high in the west and a more subtle gravity

trend in the east, see Figure 3. The aeromagnetics indicates a large open Z-parasitic fold and a

regional scale NW trending cross structure.

The MLEM survey identified a NE trending moderate bedrock conductor situated on the flank of the

subtle eastern gravity trend. Modelling of the conductor indicates a depth to top of source of <125m,

a steep NW dip of 80-850, a moderate conductance of ~1,250-2,000S+ and a plate with dimensions

of ~800m x 800m+ (summarised in Table 2). RC drill testing of this feature is required to determine

the source of the conductor.

Future Programmes

MLEM surveying will recommence in late January to complete untested targets from the 2015

programme, i.e. Areas A North and South.

RC drill testing of four conductors at Area D and one at Area F is planned for late

February/March.

A +10,000m aircore programme is planned to commence next quarter, aimed at providing

valuable geological and geochemical information and assisting with the prioritisation of areas for

further work.

Further details of the drilling programmes will be released once final planning and logistics are

complete.
